*
Data from the diet record and FFQ were natural log-transformed, calculations performed, then answers back-transformed and multiplied by 100 %.
†
‘FV-adjusted’ was adjusted by the cross-check questions used in the fruit and vegetable sections of the FFQ.
‡
Mean % agreement=FFQ/diet record (%); 95 % CI=95 % CI of the mean % agreement.
